A security camera captures the damage and still images show how destructive the act was.

The owner, who was asleep at the time, said it sounded like a sonic boom. One of his working girls was inside the brothel when the big rig came crashing in. She said the whole building just shook and there was chaos everywhere.

Although the front of the brothel suffered extensive damages, no injuries were reported as a result of the crash.

Police said the suspect was wearing a bullet-proof vest and a mask when the incident occurred. Bunny ranch owner Dennis Hof said he saw Brandt wearing a helmet as well.

Authorities still haven't released a motive behind the incident, but a friend said the man was very upset and claimed he had a bad experience at the Bunny Ranch about 20 years ago.
